- Update to version 2.2.6:
* Add initial-state p_z and inelasticity selectors for DIS (#80)
* Improve the reweighting to include the local K=BBar/B factor
in MEPS@NLO runs (#73)
* Improve treatment of the shower reweighting scale cut-off, it
is now applied also when reweighting AlphaS and the PDFs in
the CKKW clustering sequence (also mentioned in #73)
* Adapt status=4 convention in the short HepMC output (#79)
* Compute approximate NLO EW corrections (and subleading orders)
as on-the-fly alternative event weights (#41). See Example in
Manual for details. Currently only works with a
soon-to-be-released version of OpenLoops.
* Add a filter between the perturbative and the non-perturbative
event phase, which can be used to reject events with
parton-level cuts (!94)
* Bug fixes:
- Fix NLO and Variable Selector routines (#70, #88)
- Fix unweighting treatment for the LocalKFactor (and its
on-the-fly variations) in negative events (#94)
- Fix argument validation in
GGH_KFactor_Setter::ClusterMassCorrectionFactor
- Fix core scale setter for DIS when the incoming particles
are ordered ep instead of pe and adapt it for ee->xy (where
xy is not a quark pair) (!81)
- Fix strong coupling reweighting in merging runs in cases
where nothing was clustered (#66)
- Fix beam remnants for DIS setups
- Fix rejection of rare negative-energy configurations in the
shower (#44)
- Fix treatment of negative UserHook weights in HepMC
interface (#100)
- Fix a mapping in the OpenLoops parameter-setting interface
(#87)
- Fix HEFT Higgs production with COMIX (#114)
- Fix compatibility issues with recent versions of Rivet
- Fix error when compiling with MCFM support
- Fix compilation on ARM/PowerPC architectures
- Make environment importing when building scons scripts more
bullet-proof
- Fix compilation of the HZTool interface add-on
- Drop SHERPA-MC-fix_arm_build.patch: fixed upstream.
- Rebase SHERPA-MC-no-return-in-non-void-function.patch: partially
upstreamed; fix new error introduced.

- Update to 2.2.5:
* Interface changes
- Add preliminary support for HepMC3 (this interface is still
being tested)
* New features
- Improve decay showering off top quarks
- Improve single-top support and add examples and documentation
for its production channels
- Improve hadronisation and hadron decays for heavy flavour
production
- Introduce a user hook framework which allows users to easily
implement
event generation afterburners, see Examples/Userhook
- Add settings to output ME-only on-the-fly variations (along with
the full ones):
HEPMC_INCLUDE_ME_ONLY_VARIATIONS=1 (HepMC interface)
- New cut-off for parton-shower reweighting:
CSS_REWEIGHT_SCALE_CUTOFF=<pt_min>, default: 5 GeV2
this is more generally applicable than using a cut-off on the
number of reweighted emissions
- Improve support for on-the-fly variations of clustering steps
(reweight each step locally instead of doing it globally)
* Bugfixes
- Fix issue with the overweight treatment for negative weights
- Add missing shower weight in some event outputs, e.g. when using
`OUTPUT HepMC...[]`
- Fix issue with the overweight threshold for on-the-fly variations
- Fix issue with non-trivial beam spectra handling
- Fix possible issues with electron-"PDF" initialization
- Fix issue with the ISR-channel threshold for leptonic collider
- Fix X/Y functions in METOOLS (this is relevant for hadron decays)
- Fix crash in decay-channel sorting
- Fix crash when using EVENT_TYPE=HadronDecay
- Fix issue with CSS strong coupling values when using non-trivial
scale factors
- Fix issue with QSF variations for real emission calculations with
COMIX
- Fix crash when doing on-the-fly variations and invalid dipole
kinematics occur
- Fix issue in the interplay of the flux and the BIWeight for 1 -> n
processes
- Fix issue when using vertices with a vanishing coupling
- Fix rare "invalid amplitude" crashes
- Fix issues when adding limits for the number of t-channel propagators
in matrix elements
- Fix issue with checking PDF availability when enforcing jet vetoes
- Fix several compilation issues
- Add patch to fix ARM (and PPC) builds:
* SHERPA-MC-fix_arm_build.patch
- Refresh partially upstreamed patch:
* SHERPA-MC-no-return-in-non-void-function.patch

- Upstream released a new 2.2.4 tarball, so refresh sources.
-------------------------------------------------------------------
Sat Sep 2 14:19:14 UTC 2017 - badshah400@gmail.com
- Update to version 2.2.4:
* Interface Changes:
- New default parameters for hadronisation model to improve
heavy flavour production fractions and meson/baryon ratios.
- Updates to Recola interface with some new parameter (names),
please refer to the manual.
- Make STRICT_METS the default scale setter to guarantee full
scale setting accuracy for unweighted events.
* New features
- Availability of DIRE NLO parton shower (cf.
arXiv:1705.00742). This is not (yet) the default shower, in
particular not in NLO-merged configurations.
- Higher numerical stability in parton shower kinematics
(re)construction.
- Add OVERWEIGHT_THRESHOLD allowing user to cap maximal weight
during event generation (cf. manual).
- Avoid spuriously large weights in NLO-merged samples due to
instable PDF ratios.
- Add interface for hadron-level selectors.
- Add Max_N_TChannels option in Amegic.
- Add possibility to identify partons which originate in the
hard decay handler.
- Restructure gzip support such that it can be switched off at
runtime (USE_GZIP).
- Enable on-the-fly reweighting for calculations with the
Higgs (Interference) add-on for HIGGS_INTERERENCE_MODE 1, 2,
3 or 4.
* Bugfixes
- Bugfix in NLO-matched parton shower emission for non-trivial
colour structures like in V+2j@NLO. This fixes an eta
asymmetry which was visible at the ~2% level in such
samples.
- BSM models through UFO: fix running coupling behaviour and
treatment of exotic color octets.
- Bugfix in random generator for Poisson distributions with
large mean values.
- Bugfixes for segfaults and compiler warnings with gcc 7.1.
- Bugfix for colour assignment in clustering for loop-induced
merged processes.
- Bugfix for decay showering in conjunction with NLO+PS
matching.
- Change BuildRequires HepMC-devel to HepMC2-devel: not compatible
with HepMC >= 3.0.
- Rename libSHERPA-MC-config to libSHERPA-MC0-config that follows
the shared lib versioning. In addition the ld.so.conf.d file is
also renamed to follow the shared lib version to make it
possible to install multiple versions of the shared lib.
- Rebase SHERPA-MC-no-return-in-non-void-function.patch and add
fixes for one more function showing the same issue in version
2.2.4.
- GCC >= 6.0 required, build fails with older GCC for openSUSE <=
1320.
-------------------------------------------------------------------
Fri Apr 28 06:47:09 UTC 2017 - badshah400@gmail.com
- Update to version 2.2.3:
* Support for the Recola one-loop generator for QCD corrections.
- Add SHERPA-MC-no-return-in-non-void-function.patch -- Fix a
non-void (bool) function that was not returning any data to
return "true".
-------------------------------------------------------------------

alpha_s variations in the matrix elements for LO, LOPS, NLOPS,

Sun Jun 22 00:41:33 UTC 2014 - badshah400@gmail.com
- Update to version 2.1.1 (Bug-fix release):
+ A bug related to MC@NLO has been fixed. This will affect the
total cross section in heavy quark production at the level of
few permille.
+ A bug related to parton showering in associated Higgs boson
production has been fixed.
+ A problem related to SQLite database locking on IBM BG/Q
systems has been solved.
+ A bug related to CS subtraction with Comix has been fixed.
This will eliminate possible large weights in events
containing extremely soft gluons.
+ A bug related to the QED corrections on the hard interaction
accidentally being switched off has been fixed.
+ A bug related to the contents of the HepMC::PdfInfo? object
in MC@NLO event generation has been fixed.
+ A bug in the underlying event simulation, presenting as a final
state particle asymmetry, has been fixed. An update of the
underlying event parameters was necessary, invalidating MPI
grids generated with previous versions.
+ The Python interface to access Sherpa's matrix elements has
been updated and supplemented with a C++ interface.
+ A bug in the CS subtraction in DRED has been fixed.
- Changes from version 2.1.0:
+ Introduced SQLite as the preferred storage manager
+ Spin correlated decay chains (Comix only), includes all 1->2
and 1->3 decays allowed by the model, iterated to arbitrary
decay chain length, all decay steps are dressed with QCD
parton showers and QED corrections
+ MC@NLO H events with Comix, speeds up initialisation and
runtime
- Packaging changes:
+ Disable rivet bindings until SHERPA-MC builds with latest
Rivet >= 2.1.2
+ BuildRequires on sqlite3-devel introduced since version 2.1.0
+ Package new binaries init_nlo.sh, make2scons, plot_graphs.sh.
